[aklug] Re: Linux/Unix VM's for Demonstration.

Seems academia is even slower on the uptake as technology (Linux) has
evolved :-(. I might sugest you could kill two birds with one stone if you
were to take a look at Proxmox .... http://pve.proxmox.com/wiki/Main_Page
along with a bare metal Linux based Virtual environment they also have a
nice selection of Virtual appliances. For demo purposes you could run it on
a laptop ..... Standard YMMV disclaimer applies :-)

It would be really tough to show the true power of the dark side er linux.
You can run it from a single floppy. You can have it running your high end
multi-core systems. You can install it on your linksys router. I had a tv
that looked like it was running it. Or you can have it running a beowulf
cluster.

Hi everyone,=20

TL;DR: going through a very one sided PC OS course. Instructor is great =
but didn't set the curriculum, which is horrible. I have been asked to =
build VM's to demonstrate a view OS's. I would like suggestions on which =
VM's to demonstrate.Would also like help with a simple explanation of = why
unix is not linux and vice versa.
(for those who DON't read www.reddit.com on a regular basis, TL;DR=3DToo =
Long, Didn't Read)

I am currently going through a PC operating systems course. It's = required
for my degree. It is, to say the least dreadfully one sided in = favor of
Window$. Recently sat through a lecture that was supposed to = familiarize
you with various choices for OS's. 59 slides of which 49 = were about
windows. 4 were about Unix/Linux that contained the following =
quotes:

UNIX System V Release 4
Two main design standards:
Berkeley Software Distribution (BSD)
System V Release 4 (SVR4) =96 Linux is an example This book uses Linux for
its UNIX examples"

"Some UNIX versions provide you with a GUI X Window is the most popular"

"Most UNIX versions come with different =93shells=94 or user interfaces =
and it is up to the user to pick the shell they wish to use Most shells
function in the same way" ~ with no explanation of what a = shell is,
remember this is a 100 level class.

As a screen shot of Unix System 5 R4 they provide a screen shot of = Fedora
Core.

and this is my favorite:=20

"Most versions come with a line editor that is used to create text one =
line at a time A text editor enables you to edit text in a full-screen mode"

with absolutely no further explanation of why you would need such a = thing,
no mention of configuration, that the OS is primarily text files = and that
this is how you configure the system. no mention of almost = anything that
makes Unix OR Linux different than any other OS. These = quotes above are
literally the entire meat of what was mentioned about =
*nix.=20

For your further amusement I present the lecture "summary"

"Early computer operating systems were primitive compared to current =
computer operating systems but were significant during their time and =
moved us toward a desktop computing environment The Windows, Macintosh, and
UNIX operating systems are popular current = operating systems, with new
releases being announced on a regular basis Server operating systems have
evolved to allow clustering, virtual = servers, self-healing NTFS, storage
manager for SANS, single sign-on, = network management, and security
features Mac OS X is built on Darwin UNIX, which is a distribution of the
BSD = UNIX version. With the release of Snow Leopard, the operating system =
runs only on Intel-based chips."

So, I have been asked to help the class by building and providing some =
VM's of various OS's so that can see some variety of what is available. =
I've already done a couple of versions of windows (svr2k8r2, win7, =
win8beta). I'm doing Solaris 11 (because I am a Unix guy, = professionally),
I can't do a VM of OSX for licensing reasons but I have = my MBP. So that
leaves Linux=85

I intend to start off with the current version of Ubuntu with several =
different windowing systems loaded and switch between them so they can = see
that it's the same OS but looks completely different. I would also = like to
load a couple of different shells so I can demonstrate how the =
differ.=20

So my question for the group that I would like help with is twofold:
1, Of all the multitude of Linux distros available, what are some of = the
most unique (and specialized) that are available that I can use to =
demonstrate how versatile Linux is?

2. Help with a simple demonstration of the classic statement "Gnu's Not =
Unix". I.E. help me explain as simply as possible why Linux and Unix are =
so similar but are entirely different animals.

Thanks for taking the time to read my long winded output, and I would =
appreciate any creative/constructive input.
